Cement Kiln Cooler Air Requirement

Cement kiln dust is a major waste to the air environment and needs collection and disposal to protect the surrounding air. Kessler (1995) reports that typically each percent of dust wasted increases the specific heat consumption by about 0.7% and decreases clinker production by 0.5%.
